Final Environmental Impact Report
Project Description: Development of the proposed project would include the construction of 188 single-family residences, associated roadways and infrastructure, a 15.5-acre public park and a new 15.8-acre equestrian boarding facility on approximately half of the total 259-acre project site. The majority of the residential lots would be clustered on a graded, centralized plateau currently used for ongoing filming operations and grazing. Hidden Creeks Estates is planned as a gated community with 158 single-family residential lots and 25 residential equestrian lots along with a public park and an equestrian facility. The undeveloped portion of the project site would be preserved as parkland and open space. The envelope of open space surrounding the project would buffer the proposed residential development from the existing community of Porter Ranch to the east and south and would complement adjacent open space areas, including the Michael Antonovich Parkland, which lies just beyond the northern and western boundaries of the project site. Primary access to the project site is proposed via a new roadway extending from the current northern terminus of Mason Avenue and connecting to the northeast edge of the project site, near the proposed park. The road would traverse through an easement to be granted to the City of Los Angeles by Southern California Gas Company. The project would also involve the construction of internal streets and cul-de-sacs to provide access to the 188 proposed individual lots. Browns Canyon Road would provide secondary emergency access to the site and surrounding area. Public access to the equestrian facility would also be provided from Browns Canyon Road. Construction of the proposed project would involve demolition of the existing single-family residence and associated equestrian facility. Following demolition, the project site would be graded, with an estimated 6.8 million cubic yards of earth material being moved. All earth material would remain on the project site, as no dirt would be imported or exported as a result of project construction or operation. Upon completion of site grading, project infrastructure would be installed followed by construction of the 188 single-family residences and the equestrian facility. The project site is currently located in an unincorporated portion of Los Angeles County. Implementation of the proposed project requires an amendment to the City’s sphere of influence that must be approved by LAFCO as well as the annexation of the property to the City of Los Angeles. The project site would then fall within the Chatsworth-Porter Ranch Community Plan Area. Therefore, Citywide General Plan and Community Plan amendments would be required for the annexed project site to correspond with the proposed land use and zoning designations. Proposed zoning and land use designations are shown in the attached figures.
